SAFETY DEVICE 1 0a 'ERorLANEs.

Specification of Letters Patent.

Patented Oct. 10,1911.

Applicationfiled June 22, i910. Serial No. 568,380.

To all whom "it may concern:

Be it known that I, HENRY W. MAT'rONI, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Safety Devices forAeroplanes, of which the following is a specification, reference beinghad therein to the accompanying drawing.

My invention relates to'means and mechanism for facilitating the landingof aeroplanes, and insuring against the falling of the plane in case themotive power fails, and has for its object the provision of a safetydevice very simple in construction, easy to operate, andwhich willinsure safety in landing after a flight, avoiding any sudden concussionwith the ground, enabling the operatorto effect a landing with greataccuracy in a small space.

To attain" the desired end, my invention consists in certain novel andusefulcombinations or arrangements of parts, and pe culiarities ofconstruction and operation, all of whicliwill be hereinafter first fullydescribed, and then pointed .out in the claim.

In the drawing, Figure .1 is a plan view of my safety device applied tothe upper Similar numerals of reference, wherever, they occur, indicatecorresponding parts in all the figures.

'1 is the plane of an aeroplane, either a monoplane or biplane, providedwith. the

usual framework 2'for connecting-themechanism, etc, to be supported.

3 are supplementalfsafety planes, connected to the plane l by means ofrods 4 hinged at 5 and 6.

7 are springs which automatically throw the safety planes to an elevatedposition and extend the same, when desired.

8 are fingers carried by the supplemental planes, arrangedto engage arotatable arm 9"when said planesare folded down in an inoperativeposition. The arm 9 is carried by a vertical, rotatable shaft '10,provided with a manipulating wheel 11 which is located within easy reachof the operator.,

I have shown all of the planes as substantially flat, but it is obviousthey'ma'y have any preferred shape and configuration,

bemade of any appropriate material, and

be used in any desired number, and in any. position, without departingfrom the spirit of my invention.-

Having now fully. described my invention, what I claim as new therein,and 'desire to secure by Letters Patent, is: a

In a device of the kind described, the combination-with a plane, ofsupplemental planes. pivotally'mounted on the firstmentioned plane,fingers carried by said supplemental plane, springs for moving saidsupplemental planes in an operated. position, and a rotatable arm'forengaging said fingers forfholding said-supplemental planes in aninoperative osition. In testlmonyw ereo-f HENRY W.- MATTONI. Witnesses:
